Early Life and Background

Interestingly, she did not come from an established entertainment background. Her passion for the performing arts was entirely self-discovered, standing in stark contrast to the athletic interests of her immediate family members.
Her first introduction to the stage occurred during a primary school play at Taverners Hill Infants School. She played the lead role in a unique, musical adaptation titled Little Red Rocking Hood, which officially ignited her lifelong passion for acting.
She later attended the prestigious Newtown High School of the Performing Arts in Sydney. This environment allowed her to immerse herself fully in dramatic studies alongside other ambitious young creatives.
“Great art often demands a leap into the complete unknown.” In 2018, during her final academic year, she made the incredibly bold decision to drop out of high school entirely to pursue a demanding, full-time television role, prioritizing real-world experience over traditional schooling.

Early Australian Television

To sustain herself financially between early auditions, she frequently appeared in regional television commercials. She featured in prominent national campaigns for massive brands like Cadbury, Woolworths, and KFC.

The role demanded an intense mixture of sharp comedic timing and profound vulnerability. Her performance was universally praised by domestic critics, officially marking her as one of Australia’s most promising young dramatic talents.
